Abstract

Progress in learning reflects itself in a number of different ways: increase in the rate, probability of occurrence, speed and vigor of responding, decrease in latency (time required to initiate a response), time required to complete a task, and number of errors committed in doing so. These changes in performance are frequently presented in one of a variety of forms called learning curves, in which the baseline is most often the number of practice trials but occasionally is time. The vertical axis represents one of the measures just mentioned.
